Professional Dripless ETS3000EL Caulking Gun
The Dripless ETS3000EL is a lightweight, professional caulking gun designed for decorators who want smooth, consistent beads with less mess. Built to accept both 300ml and 400ml cartridges, it delivers a powerful 18:1 thrust ratio that makes light work of thick construction adhesives, polyurethanes and high-viscosity sealants.
An ergonomic handle, rotating barrel and rugged composite frame help you work comfortably in tight spaces, while the optional dripless function gives you precise control when applying acrylic or silicone caulk. Pair it with your favourite caulks and sealants for cleaner joints, sharper lines and a more professional finish on every job.

What the Dripless ETS3000EL Is Best For
This professional caulking gun is a great choice for both trade decorators and serious DIYers who need reliable control and clean results. It’s particularly suited to:
- Applying acrylic and silicone sealants around windows, doors, skirting and trims.
- Using thick construction adhesives on timber, MDF, plasterboard and metal.
- Sealing bathrooms, kitchens and wet areas with sanitary-grade sealants.
- General interior and exterior decorating where a neat, consistent bead is essential.
How to Get the Best From the Dripless Function
The ETS3000EL lets you adjust the pressure depending on the type of material you’re using:
-
For thick products (construction adhesives, polyurethanes, heavy sealants):
Turn the dripless function OFF to maintain constant pressure on the cartridge. This makes it easier to push out thicker materials without stopping and starting. -
For acrylic and silicone caulks:
Turn the dripless function ON to release pressure as you let go of the trigger. This helps prevent the material from continuing to flow, reducing mess and giving you a cleaner bead.
For best results, always cut the nozzle to the right size for your joint, hold the gun at a consistent angle and work at a steady, controlled speed.
